Thanks fr the advise,I will keep searching
On a side note,here in Japan TCS does not allow any other placement of any of the front suspension besides the springs. This includes the servo saver and servo position. Its really an odd way of doing things but I think they do it to keep the car easy to drive and not so twitchy.

There is nothing "Twitchy" about this car
It is so smooth and easy to drive
I think more due to thin flexible chassis, than any servo position

It is easy to drive but have to tried the other servo mounting positions? I have tried it just about every way you can think of. The feeling of the chassis changes alot from the normal steering postion.
You car is not to real TCS specs,its the hacked up US TCS spec. its a completely different animal useing Japan specs,I should have said that earlier.
Its a lot lighter in the rear using Japan specs.
But it is interesting to note the have restricted the servo set up.

Hope to have it wired up soon.
Found a simple way to use standard 64p spur gears.
72t will not clear the diff backing plates, 78t fits fine.

Standard 12th rear wheels fit, but maintaining ride height will require larger diameter tires than most 12th scale cars run, Tamiya apparently wanted this car to run 52-45mm tires, try much smaller than that and the chassis will run out of clearance.
Options I see are to use Tamiya RM-01 foams, or F1 foams.
Full size Jaco Rear tires will work, just...

To check max rollout, that's a 78x55 gear for 116+mm roll and stock 52.5mm tires.
Gear selection shouldn't be an issue for 17.5 blinky 1s where 85-110mm roll are the average over a broad range of motors and tracks.

Redbull, where can I pick up a 78t 64p spur gear that you reference here? I want to try your conversion for 64p spurs.

I've noticed that the front tyres (kit) seem to wear quicker than the rears. Is this more to do with my driving style (or lack there of ).

Love this car, it's so easy to drive fast. Is there any benefit to buying the Carbonfibre chassis?

thanks

The front tires do wear quickly, even on carpet. The option fronts work as well or better and last much, much longer.
The option rears also work very well and seem to free up the rear a tiny bit but still keep great rear grip. Both kit and option rear tires hold up very well.
